embedded-real-time-software-engineer

Guides embedded real-time firmware—MCU tradeoffs, bare-metal vs RTOS (FreeRTOS/Zephyr patterns), task priorities/deadlines/jitter, ISR deferred work, stack/heap policy, WCET/timing analysis, concurrency and priority inversion, drivers/HAL, JTAG/SWD/trace, power modes, MISRA C awareness, safety-aware automotive/medical/industrial patterns without certification claims. Use for embedded firmware, RTOS scheduling, drivers/HAL, IRQ design, memory policy, WCET, bring-up, low-power—not HIL security (hardware-in-the-loop-security-tester), backend apps (senior-software-engineer), SCADA/OT (scada-ics-cyber-security-specialist), server perf (performance-engineer), RTL-only without firmware, CI gates (build-validator), tiering only (mission-critical).
